Decision memory vs Confluence

Confluence is a mature team wiki — built for documentation at organizational scale, with permissions, spaces, and structure suited to larger teams. It's a documentation tool at its core, which means it answers "what's true right now," not "what did we decide and why."

The short answer

If you need a wiki for how-tos, runbooks, and living documentation across a larger organization, Confluence is a reasonable, well-established choice. If what keeps getting lost is specifically the reasoning behind decisions — even ones that are documented elsewhere — a tool built around capturing that reasoning as its own structure, rather than as another wiki page, will hold onto it more reliably.

Where they actually differ

Primary purpose: Confluence: documentation and knowledge base at organizational scale. Cadenzova Decisions: a memory of decisions and the reasoning behind them.
Update model: A Confluence page is typically kept current — edited in place as things change. A decision record in Cadenzova Decisions is a point-in-time capture: what was decided, when, and why, plus its eventual outcome — not something that gets silently rewritten.
Connections: Confluence links pages if you add them. Cadenzova Decisions proposes relates-to/supersedes/contradicts links between decisions automatically as they're captured.
Finding the reasoning later: In Confluence, that depends on someone having written a dedicated decision or ADR page and everyone knowing to look for it. In Cadenzova Decisions, every entry goes through the same reasoning structure, and you can also ask a direct question and get a grounded answer.

Choose Confluence if…

You need a wiki for living documentation, runbooks, and knowledge at scale, with the permissions and structure larger organizations typically require.

Choose (or add) Cadenzova Decisions if…

The specific thing you keep losing is the reasoning behind decisions — including ones that might already be mentioned somewhere in Confluence, buried in a page nobody thinks to check.

Where they overlap

Many teams already keep a "Decisions" or "ADR" space in Confluence — that instinct is correct, and it's exactly the gap decision memory is built to fill more deliberately: structured capture, automatic connections between related decisions, and a grounded way to ask "why" instead of hunting through pages. Running both isn't redundant — Confluence for documentation, Cadenzova Decisions for the decisions themselves.

If your Confluence "Decisions" space is really an ADR log, see What Is an Architecture Decision Record? — or read What Is Decision Memory? for the broader concept.
